LIBRARY-STACK CONSTRUCTION.

Specification of Letters Patent.

Patented Feb. 15, 1916.

To all whom it may concern Be it known that I, \Vannnn B. Loon a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Libraryfitack Construction. of which the following is a specification.

The object of this invention is to provide an improved form of library stack or a support for book shelves, floors etc. in tire proof library construction.

Another object of the invention is to make the support entirely of sheet metah the support being made of uprights arranged in pairs, the uprights being welded together at their meeting edge.

Another object of the invention is to provide bearing plates between consecutive sections in the stack.

Another object of the invention is to provide cover plates for the tops of the stacks, which cover plates are removable to provide for additional section in the stack.

Another object of the invention is to provide tie rods for the caps to hold the tops of the uprights in line with each other.

These and other objects of the invention, will be fully illustrated in the drawings. described in the specification andpointed out in the claims at the end thereof.

In the accompany drawings. Figure 1 is a perspective view of my improved stack construction. Fig. 2 is a detail perspective view of the construction shown in Fig. 1 in which bearing plates are interposed between consecutive sections. Fig. 3 is a detail perspective view of one of the bearing plates. Fig. 4 is a horizontal section on the line I -I in Fig. 2. Fig 5 is a perspective view of the cap used for finishing the tops of the channels shown in Fig. 1. which caps can be removed to permit additional sections to be placed on the tops of the channels. Fig. 6 is a front elevation of the cap in place on its channel. Fig. 7 is a front elevation of the cap separate from the channel. Fig. 8 is a side elevation of the cap separate from the channel. Fig. 9 is a detail perspective view of one end of the cap showing the recess therein. Fig. 10 is a perspective view of the top of the section on which the cap fits.

In the accompanying drawings. like reference numerals indicate like parts.

In the drawings. the uprights 40 are shown made up of the main channels 41 and 42 both of which are U shaped. the channels being made relatively wide. These channels are each provided with the wide lianges thereon 43. ll. 45 and lb which flanges are llarcd upwardly and out and are provided with the meeting edges l7 and 48. .\t the ends of the channeled sections thus formed. the meeting edges l7 and l8 and thc flared or beveled portions adjacent thereto are cut away to receive the bars 18 with which bars the channels are thus interlocked. The flanges l and 45. H and ll) are separated from each other just enough to receive the bars 18 between them and the flanges and the bars are perforated to receive the bolts 49 and 50 and similar bolts on the other side. not shown. the arrangement of which bolts. howevcr. correspond to that shown in Figs. 1 and By these bolts the channels t1 and 42 of consecutive sections are fastened together and are fastened to the bar 18. The bar 18 is perforated to receive the bar 29 which passes thercthrough and the channels 41 and 42 are recessed to receive the bar 29 which bar extends continuously through a number of sections and has threaded ends to receive the nuts on the outer ends thereof by which all of the sections are tied together.

The sections are spaced apart by the sleeves or tubes 30 through whichthe bar 29- passes. one of which of proper length is interposed between two consecutive uprights. The bar .29 passes through the uprights while the sleeve 50 abuts against the uprights and between the tension of the bar 29 and the compression of the sleeves, the uprights are held in a rigid structure. The channels 41 and 42 are perforated as shown at 5l5l to receive suitable brackets for the purpose of supporting book shelves which brackets and shelves form no part of this invention.

It will be seen that the U shaped part of the channels 4i and 42 may be of any desired width or depth. For the purpose of improving the stability of the uprights when assembled one on top of the other. I provide the bearing plate 55 shown in Fig. 3. two of which bearing plates are provided at the joint between the two consecutive sections and the uprights. This bearing plate consists of a flat plate having a semithereir t itlils H? i i react .1

downwardly tiara-twin for the pur nes t making positivt fliifWLfiflll lii with the multie tuls of the. rim. a ls ii and ii. ,l! i also finished with ilia' edges It. and 4$) ii ncr as the bca; in; slllia c between he bearing plate and the channels and it s "at away at 2 to re ive the tin hing nut.

For the purpose f closing the tops of the upright channels. whi h otherwise would re main open, I proyide the caps (35 which aps arc rectangular to conform to the channels. Cach top is preferably of a single hollow casting. It is also provided with the projections (36 and ($7 on each side thereof to cover the flanges -13, 44, 45 and 46. It is provided with the lugs 69 and (39 which engage with the inside of the channels 11 and 42. It is also provided with the projections T0 and T1 placed in the projections (36 and (37, which engage with the recesses in the cutaway portions of the flanges. These projections are provided with round holes 72 and T3. ings in the flanges and the openings in the projections T0 and T1 for the purpose of firmly securing the caps to the uprights. The caps on each end are provided with a recess such as is shown in Fig. 9. In each recess is a stepped annular surface comprising the steps 75 and T6. The surface 76 engages back of the channel and the surface T5 is flush with the channel. Through the center of the annular surface the opening TY. through which passes the tie rod 2!). When the parts are assembled as above dert'l'l l'll a hcxagtn or square nut is first put in the end of the tie rod and drawn up snugly against the surface 75 and thc chan nel. The round nut (i1 is finally put on the end of the rod 2. it being provided with a threaded recess to make engagement therewith.

()n top of the cap is provided the lug 80, having a cylindrical opening 81 therein, in which is threaded a set screw 82. Through this opening passes the tie rod 83 which engages other caps as well and by which the uprights are firmly spaced apart at the top. The rod 83 runs parallel to the bars 18 and serves the same purpose as the bar 18 in spacing apart the uprights. The bar 18 serves the additional purpose of supporting the floor.

As shown in Fig. 1. a clip 90 may be fastened on the tie rod 29 and held against the upright by the sleeve 30. To this clip may be fastened the diagonal brace 91, the lower end of which may be fastened to the btttolii of the next adjacent upright in any suitable manner.

I claim 1. An upright support comprising sections each of which is made up of a pair of The bolts Ti pass through the opentions each of which is made up of a pair of channels having outwardly extending mecting edges, a supporting bar extending across the sections between said channels, a bearing plate interposed between consecutive sections on each side of said supporting bar -a bar extending transversely of said supporting bar, a depression in said supporting plate to receive said bar, a cap for covering the end of said bar and a recess in the edge of said supporting plate to receive the end of said cap.

4. An upright support comprising sections each of which is made up of a pair of channels having outwardly extending meet ing edges, said meeting edges being partly cut away on opposite sides of said sections at the ends thereof, a cap for covering the opening of the top section, said cap conforming to the outline of the end of the section and having depending lugs that engage With said cutaway portions.

.3. An upright support comprising sections each of which is made up of a pair of channels having outwardly extending meeting edges, said meeting edges being partly cut away on opposite sides of said sections at the ends thereof, acap for covering the opening of the top section, said cap conforming to the outline of the end of the section and having depending lugs that engage with said cut away portions, bolts extending through said lugs and said meeting edges to fasten the cap to the section.

(3. An upright support comprising sections each of which is made up of a pair of channels, a bar extending across the top of said section, a recess in the top of said section to receive a part of said bar, a cover for said section having depending lugs therein 4. which engage inside of said channels, said cover having a surface adjacent to each of said lugs, said surface being continuous with the surface of the channel when the cap is in position.

7. An upright support comprising sec tions each of which is made up of a pair of channels, a bar extending across the top of said section, a recess in the top of said section to receive apart of said bar, a cover for said section having depending lugs therein which engage inside of said channels, said cover having a surface adjacent to each of said lugs, said surface being continuous with the surface of the channel when the cap is in position, an opening through said lugs and surface to receive said bar.

8. An upright support, a cap for said 10 support, a lug projecting above said cap, a
